Raphidophora Beccarii, Engl., Pflzrch, XXXVII (IV, 23 S), Arac.-Monster., 

 46, fig 20; Becc, Mal., 1, 270, tab. XIX, fig. 6-9. 



The spécimens occurring in the Buitenzorg Herbarium differ from 

 Engler's description given in Pflzrch in having the pétiole + 15 — 35 cm. 

 long, the lamina ± 25—50 X 8—20 cm., the laciniae 1—4 on a side, the 

 lower elongate-triangular from a dilated base, curved or flexuose, the higher 

 not rarely broadly linear from a dilated base with the apex obliquely 

 truncate, the postical corner rounded, the antical corner finely falcate- 

 acuminate, the peduncle + 10—20 cm. long, the spadix ^,4— l'/z cm. 

 diam., mostly equally cilindrical, the stigmata depressed or impressed in 

 the centre— NiEUWENHUis' No. 1920 from Bornéo has the laciniae pierced 

 at the base with longitudinal, narrowly oval holes V2 — 2 cm. long. 



Raphidophora crassifolia (Engl.), v. A. v. R ; Epipremnum crassifolium, 

 Engl., Pflzrch, XXXVII (IV, 23 B), Arac.-Monster., 63, fig. 26. 



According to Engler's diagnosis and figure (ovaria 2-locularia, ovulis 

 in quoque loculo 2) this is a Raphidophora like R. tetrasperma Hk.f. and 

 not an Epipremnum (ovaria 1-locularia, ovulis ad placentam parietalem, 

 singularem 2 — 8).

 tim incisa, basi rotundata; segmenta lateralia patentia vel patentissima, 

 linearia, subfalcata, basi foraminis (1 raro 2), oblongo-ovalibus vel 

 obtuse triangularibus, '/2~2 cm. longis saepe munita, mediana maxima, 

 + 12'/2-25 X 2V2-5 cm., ubique aequilata vel apicem versus subdilatata, 

 apice oblique truncata, latere antica subacuta, latere postica obtusa vel 

 rotundata; segmentum terminale rhomboideum; venae primariae in quoque 

 segmento laterali 2, raro 3, venis secundariis gracilioribus 5 -7 interpositis.
